Each member body interested in a subject for which atechnicalcommitteehasbeenestablishedhastherighttoberepresented on that committee. International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 2160 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This International Standard specifies a method for the determination of the corrosiveness to copper of liquid petroleum products and certain solvents. Volatile products, having a maximum vapour pressure of 124 kPa at 37,8 °C are included. Volatile products with a vapour pressure above 124 kPa at 37,8 °C should be tested according to ISO 6251 (see caution below). Electrical insulating oils should be tested according to IsO 5662. CAUTION - Some products, particularly natural gasolines, may have a significantly higher vapour pressure than is characteristic for their class, even if below 124 kPa at 37,8 °C. For this reason, extreme caution should be exercised to ensure that the pressure vessel containing such material is not placed in a bath at 100 'C. Such samples may develop sufficient pressure at 100 °C to rupture the pressure vessel and cause damage and/or injury. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
